1,10-Phenanthroline is a high-purity chelating agent widely used in analytical chemistry, especially for the detection and quantification of divalent metal ions. It binds to metals such as iron, copper, and zinc, forming stable complexes that are easily detectable in laboratory assays. This reagent is essential in metal ion analysis, complexometric titrations, and research applications in molecular biology, where metal ions can affect protein structure and function. The 50g quantity provided ensures sufficient reagent for large-scale studies and repeated analyses in research and industrial labs focusing on environmental chemistry, biochemistry, and analytical chemistry.
